You are not following standard patch submission practice as indicated here http://www.denx.de/wiki/view/U-Boot/Patches#Sending_updated_patch_versions

You need to document entire change history for each patch to be submitted below ---, this is important

Wrong style for multiline comments, pls refer chapter-8 @

Sorry for mistake..
Do i need to add history in each patch or first patch of a series patch?
I mean if I am submitting 2 patches in series I define history in patch 1/2.
Am I right?

Thanks & Regards,

You should add relevant history for each patch, if in your patch series one patch is being changed, change log for that particular path is must for other patches you may say, "Not changed in this version"

You may refer some other patches submitted/accepted on the list.
